FIRE-BACK'FOR sTovEs.

SPECIFICATION forming part of Letters Patent No. 341,851, dated May 1.1`1886.

Application tiled April 25, 1885.

To all whom zit may concern:

Be it known that I, JOHN W. KEYES, a citizen of the United States,residing at Chicago, Illinois. have invented a new and usefulImprovement in Fire-Backs for Stoves, of which the following is aspecification.

My invention is an adjustable fireback for stoves. j

My invention consists in the arrangement of several pieces placedtogether so as to be moved one upon another, so as to vary the height orlength of the fire-back, and also in providing projections upon certainparts and recesses or openings in other parts to receive thoseprojections and enable the parts to be secured together in position.

In the drawings, Figure l is a view of the back side ofV my tire-back,one end being broken away. Fig. 2 is a longitudinal section, and Fig. 3is a vertical section.

A is the main front piece, and has the bolts a secured to it by anysuitable meansthe most convenient method is to place the bolts inposition in the mold and pour the molten iron around the bolts, so thatby the contraction of the metal the bolts will be held securely inplace, and will project out from the back side of A and project throughthe recesses of the other parts when they are all placed to gether.

B is an auxiliary front piece of about the the same length as A, and isprovided with vertical slots Z, to receive the bolts aand allow the twoparts Aand B to be moved vertically so as to vary the total height ofthe tire-back.

At one or both ends of the parts A and B Serial No. 163,474.

(No model.)

are placed the extension-pieces C and D, the latter being upon the backside and provided with a slot, s, extending longitudinally so that itcan be moved in or out to vary the total length, and the piece C isprovided with a larger opening, r, which is of sufilcient sizevertically and lengthwise to allow the part C t0 be extended verticallyor lengthwise.

Notches or spaces o are formed on the end of D, and teeth or projectionsln are formed on the end of C, so that when the parts C and D are placedtogether the teeth n will mesh or project into spaces 0.and thus retainthe parts in position relative to each other vertically, v and allow thedepth of the combined parts to.

be varied as may be desired. It will be seen that the bolt a extendsthrough the vertical slotZ in the piece B, and through the large squareopening r in the plate C, and through the longitudinal slot s in thepiece D. The

Iendof the bolt is threaded and fitted with a JOHN W. KEYES.
